SPECIFICATION formingpart of Letters .Patent No. 293,509, dated February 12, 1884. Application filed lll'ovember 1Q, 1883. (No model.)

To all whom, it may concern.-

Be it known that I, CHRISTIAN L.-Pnrnn- SEN, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and Improved Feathering PaddleWheel, of which the following is a full, clear, and exact description.

My invention seeks to provide a practical feathering paddle-wheel of simplified construction; and the invention consists in pivoting the several blades of the wheel at their inner edges in the frame of the wheel, and arranging suitable stops in the frame radially beyond the pivots of the blades and near their outer edges,'which act to hold the blades to their work while passing through the water.

Reference is to be had to theaccompanying drawings, forming part of this specification, in

which similar letters of reference indicate corresponding parts in all the figures.

Figuresl and 2 are sectional elevations of my .'new and improved feathering paddlewheel,

' lateral movement upon the shaft by the collars O O;

D D representthe blades of the wheel. These are pivoted at their inner edges uponthe rods E E, which are secured at their ends in the plates A A.

Arranged radially beyond the rods E E are the stop-rods F F, against which a side of the bladesG O strikes as they successively enter and are forced through the Water by the revolution of thewheel, so that in operation the blades 0 O are held by the rods E and stops F in radial position all the time they remain in the water, and until they reach the highest point in the wheel, when they swing forward away from the rods F and assume a pendent position until they again enter the water and meet resistance, whereupon they will again assume a radial position for propulsive action, as in Fig. 2.

In order to prevent all lateral movement of the blades D upon the rods E, I place the collars G upon the rods E, between the ends of the blades and the side plates, A A, as shown in Fig. 3.

Constructed in the manner described, it will be seen that the bladesD are 'left free to revolve in nearly a full circle on rods E, to act against either side of the stop-rods F, so that when the paddle-wheel is revolved in either direction the blades will revolve in the same i direction, making a half-revolution with each full revolution of the wheel, so that they will always enter the water edgewise and remain in that position until they meet resistance,

when they will be pushed through the water sidewise by both rods E F, and thus propel the vessel. By reversing the direction of revolution of the paddle wheel, the blades will arrange themselves to their work in the opposite direction in one-half a revolution of the wheel, and the blades feather in frontand rear to all resistance, except at the workingpoint.

When the paddle-wheel is at rest, all of the blades may assume pendent positions, as shown in Fig. 1, and the wheel may be immersed in the water nearly to the main shaft 13, and yet position.

Having thus described my i nvention, what I claim as new, and desire to secure by Letters Patent, is

The feathering paddle-wheel herein shown and described, consisting of frames A, secured 011 shaft 13, and blades D, hinged at their in nor edges and adapted to be held to their work by the rodsF, placed radially beyond the'pivots of the blades and near their outer edges,

substantially as'shown and described.
